>I ignore if Alva itself had offered me a serial-to-USB cable in the box,
The Alva just offers serial, USB, and Bluetooth. If you were using a serial
adapter you'd set your Alva to serial.
>but I'm using USB since that had been advised as being autodetected.
Good. That keeps it simple. Also, brltty's autodetection defaults to being done
for USB only.
>Why should I try to complicate simple things that had worked until now ?
Well ... I didn't know exactly what had worked before so I had to ask to be
sure.
>At this moment it isn't autodetected and I can't boot normally:
>the one and only message at my braille-display says
>"ALVA Satellite OK, Waiting for connection... "
That means that brltty hasn't even connected to it.
>and Ubuntu is asking me each time for pressing U for usb, S for serial, or B
>for bluetooth, or X for exit.
I assume, here, that you're entering U.
>Once started, Orca + eSpeak work, but no braille, not in Gnome nor under
>console.
That, at least, is consistent with the other things you're reporting.
>I haven't touched my Alva, not internally nor externally. I hope it isn't able
>to change itself internally :-)
No, it wouldn't change the communication channel on its own.
>See here the brltty.conf; is that correct? :

>braille-device serial:ttyUSBttyUSB:
The braille-device operand is bad. Maybe Ubuntu's /lib/brltty/brltty.sh needs
fixing. That line should be as follows:
braille-device usb:
Also, since braille-driver is being set to al, it won't autodetect, i.e. it'll
assume Alva (which is okay in your case). Perhaps that's because you're telling
Ubuntu that you have an Alva.
>I have tried serial:USB: or simply USB: or ttyUSB:
>Nothing And Absolutely Nothing work.
You'll note above that I worte usb: in lowercase. While the device qualifier
isn't case sensitive these days, it's possible that it used to be. Please try
specifying usb: in lowercase to see if that works.
